Document Type and Number:
Japanese Patent JP2882835
Kind Code:
B2
Abstract:
A method of reducing vibrations of a car body (13) comprises a step of detection of rough which is irregular combustion in an engine (11), preferably through monitoring of angular velocity of a crankshaft of the engine (11,) and a step of exerting such external force as will cancel roll vibrations (A1) of the engine (11) caused by the rough on an engine block of the engine (11) temporarily after the occurrence of the rough. A magnitude of the force and timing of exerting the force is preferably determined on the basis of a degree of the rough and the angular velocity immediately before the occurrence of the rough.
